California Governor Gavin Newsom's decree that by 2035 all new cars sold in the state must be powered by batteries or other zero-emission systems has received strong legal and political support. The U.S. Supreme Court blocked an attempt to declare California's zero-emission mandate unconstitutional, while the EPA granted the state a waiver to deviate from federal emission standards. These actions make it harder for potential roadblocks, including President-elect Trump's opposition, to hinder California's 2035 mandate. Despite these successes, challenges remain. Legal battles are brewing, particularly around the ban on internal combustion engine sales in 2035. Additionally, there is a need to significantly increase the sales of zero-emission vehicles to meet the 100% target set by the state. Issues such as the lack of recharging infrastructure, high purchase prices, and concerns about vehicle range in rural areas could impede progress. California also faces the challenge of maintaining fuel availability for existing gas-powered cars while transitioning to zero-emission power production to meet the electricity demands of millions of zero-emission vehicles. With these complex factors at play, achieving the 2035 goal presents several hurdles for the state's ambitious plan.
